12MM X L450 X WL400 - SDS PLUS DRILL BIT (PROFESSIONAL)

The DeWalt DT9557‑QZ is a premium-grade 12 mm SDS‑Plus masonry drill bit from DeWalt’s Extreme 2® series. With an overall length of 450 mm and a working length of 400 mm, it is designed to deliver superior drilling performance in tough materials such as concrete, brick, block, and stone. The bit combines a high-grade dual-cutter carbide tip and a hardened steel body to ensure long-lasting durability and consistent, clean hole drilling under continuous heavy-duty use

Engineered for demanding professional applications, the DT9557‑QZ features the Extreme 2® tip design—two carbide cutting edges with aggressive 140° head geometry—for fast, precise penetration and excellent wear resistance. Its new 4‑flute spiral design with a reinforced central core optimizes dust removal and energy transmission, while the SDS‑Plus shank ensures secure fitment and reduced vibration. This makes it ideal for plug, anchor, and clearance holes in structural masonry work
